I had problems printing the stretchy bracelets (probably a Slic3r issue) so I whipped up a simple collar. This collar is for "Babe", change the text as desired. I used Sketchup and did not bother with any parameter scaling. I just change the name and scale the image a little bigger/smaller for each puppy. I still haven't tackled dual extrusion so I just used a marker over the name to make it stand out.
